So I just talked to Justin. He says change plugs and gap to .018 to .020. So picking up some plugs on the way home and try to get them in tonight! I drove to work and in vacuum its fine once u hit over 15psi its popping and driving like shit... so hopefully thats it.

Yeah I made sure Justin knew my full setup and we been tuning on DI only91(no PI) then 91 with PI no problems. So I highly doubt its a rich after shift condition. Now the aux coming on early and no compensation sounds more right. The car drove like shit mid 91 tune as well and we are mid E33...

I took some logs while I got on it and it was popping. Not sure whats causing it. 1st log was going thru the gears and it backfired and poped in every gear. 2nd log was 3rd and 4th and it was popping.

Honestly I was surprised I was able to get a full WOT with out it popping. Its popping alot when u get on throttle And the plugs are .22 set at beginning of tuning. Last time I said something to Justin at freek he said he switching fuel to more pi and its just running rich now. So I assume...

No, which I thought is werid. I evan looked over the newest logs for new tune i just got (E33-PI-C) and it says 33 psi is the highest it saw on 3rd gear pull. When I put on the new tune at the time (E33-PI-B) and drove it for a few days before logs were taken. it felt better i believe it was...

Lol, For some reason when I read your post saying it was the DI harness, I kept thinking of the coil pack harness that has the secondary harness that goes to the DI harness. I didn't evan think of the actual DI harness. Then when I re read all the posted suggestions again. I realized that's the...

Lol, well I Appreciate The Help Anyway! So, You were right! It was the actual DI harness. Not the one going to it. Which is the one I thought it was... so i changed it with the one from the other speed and Bam!! Problem solved!!! Thanks for your help! And Thanks to Enki and Everyone for...

Merge the whole build thread..lol jk

Yes and it seemed fine but to be sure I did it anyway just to mark it off the list of potential issues. I really just needed it to act right to get me to work and it drove and went into boost after itfp and spill valve cleaning. But after sitting in drive way and dying like 6 times over and...

Thanks man. I Appreciate The Help! I actually started there. I make the wire tuck harnesses and I have one on the car. I thought maybe I screwed it up or maybe bought wrong plug housing. But I've changed the secondary harness(The one that goes to the hpfp) 2 times. I'm on the 3rd harness now...

Ok Thanks Man! I Sincerely Appreciate The Help! ill pull itfp tomorrow and have a look.

so should i try the jumper from video before fully ripping it out or is the video questionable?

So I took spill valve off put in injector cleaner. did not change anything. still hesitates when it goes into boost and if i stay in it, it starts popping. I'm wondering how would the hpfp be locking up if it was fully broken down and cleaned (not the 1st, 2nd or 3rd time i have cleaned the...

i did the test you mentioned. the in tank pressure is 45 to 50psi. is that normal for a walbro 525 in tank pump?

Is it normal for the ap to have a zero on the hpfp lowest number seen. I've only ever seen the in tank pressure. Does that mean it's the in tank pump?

log of me trying to do the test and the car just dying.

so i let it idle to get up to temp oil was at 200F i blipped the gas and turned it off. it didn't go up. then when i went to restart it, now the car just dies fp goes up to 1800 and it drops to 400 for a sec then it starts dropping until it below 100psi then the car dies and the ap only...

im trying it now but i already changed the fprv to a different one. but doing it now anyway

Well I'm stuck. So today I made sure all ground connections at battery in trunk were tight and looked good. So i took the fprv off my other speed and it raised the hpfp idle pressure to 600 and after I blimped the gas it went back down to 400+ Went for drive same thing hesitation, popping...

No. How do u test it?
